I recently had an enquiry about a short passage from the Shatapatha Brahmana.  The passage in question is 7.4.1.1. 

Both Titus and Gretil transliterate as follows:

ātmano vā etamadhijanayati yādṛśādva jāyate 

The "va" following the "yādṛśād" is curious, and the several printed editions (Weber, etc) I checked (and asked colleagues to check...thanks to Steven Lindquist and Fred Smith) have "vai"

Is there a convention I am missing, or is this an error?

Thanks
